Description

We have a connection pool in Java and would like to use the same for our complete project where code is mixture of Clojure/Java.

(def db (ConnectionManager/getConnection)) ; #<ConnectionHandle com.jolbox.bonecp.ConnectionHandle@53371566> connection type we get after excuting this line
sql/with-connection db
(sql/with-query-results res ["select * from DummyTable where rownum <=100"] (vec res)
(map #(println (class (val %)) " " (key %)) (first res))
)
)

I believe there is a way to access the the BoneCP connection pool directly and use it with java.jdbc as-is, however it is no longer an issue for the creator of this ticket.

Hi Sean,

No, we moved to clojure based pooling in a while. We thought its better to have all stuff in clojure rather than having java+clojure. But i can give it a try today.

Thanks for your suggestion. will keep you posted.

Use the :datasource option to define your db-spec:

(def db {:datasource bonecpDataSourceObject})

I looked at the BoneCP docs and I don't see a ConnectionManager class but if you define the db-spec based on the BoneCPDataSource object, java.jdbc will call getConnection on that object to get a working connection for operations.

If we execute the above (with connection - with-query results) i get the following exception

IllegalArgumentException db-spec com.jolbox.bonecp.ConnectionHandle@53371566 is missing a required parameter clojure.java.jdbc/get-connection (jdbc.clj:192)
